Description
Technical Field
[0001] The utility model relates to the technical field of pulse bag dust collectors, and in particular to a double-layer pulse bag dust collector for welding wire production. Background Art
[0002] There are many types of welding wires, among which flux-cored welding wire is the most commonly used type of welding rod. The production of flux-cored welding wire is to fill the material into the interior of the seamless pipe to achieve a moisture-proof effect. The material inside the flux-cored welding wire is made of a variety of medicinal materials that are ground and mixed. During the preparation process, a large amount of dust will be generated and filled in the grinding tank. In order to reduce material waste and environmental pollution, a pulse bag dust collector needs to be installed outside the grinding tank to filter the dust, reduce the dust level inside the grinding tank, and separate the dust in the dust from the raised medicinal material dust.
[0003] Existing pulse bag dust collectors usually adopt a single-layer design, which cannot separate the medicine dust from the dust. The recovered mixture is not easy to be filled into the seamless pipe as medicine again. At the same time, since the particle size of some medicine dust is larger than the particle size of the dust, the large-size medicine dust is very easy to block the pulse bag during dust removal, thus affecting the dust removal effect of the bag. For this reason, a double-layer pulse bag dust collector for welding wire production is proposed, which filters the dust generated inside the grinding tank through a double-layer bag and cleans the inner bag to solve the above problems.

DETAILED DESCRIPTION
[0020] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] Example 1
[0022] like Figure 1~Figure 3 As shown, a double-layer pulse bag dust collector for welding wire production includes a grinding jar 1, and a dust removal component 2 is provided at the outer end of the grinding jar 1. The dust removal component 2 includes a side plate 201 fixedly connected to the outer side of the top of the grinding jar 1, and a hollow connecting column 203 is provided at the outer end of the side plate 201. An outer layer bag 204 is fixedly connected to the outer end of the hollow connecting column 203. An inner clamping plate 205 and a connecting plate 206 are respectively provided inside the outer layer bag 204. An inner layer bag 207 is fixedly connected between the inner clamping plate 205 and the connecting plate 206. A rotating shaft 209 passes through the outer end of the connecting plate 206. The outer end of the rotating shaft 209 is fixedly connected to bristles 2010, and the bristles 2010 are arranged inside the inner layer bag 207. The purpose of this arrangement is that the inner cloth bag 207 and the outer cloth bag 204 distribute and filter the dust generated in the grinding jar 1, so that the medicinal dust is separated from the dust, so that the recovered medicinal dust is relatively pure and can be recycled and reused. The set bristles 2010 can clean the inner wall of the inner cloth bag 207 to prevent the mesh of the inner cloth bag 207 from being blocked, which affects the dust removal effect of the cloth bag.
[0023] Preferably, the aperture of the outer bag 204 is smaller than that of the inner bag 207, and the dust removal assembly 2 further comprises a sealing ring 202 snapped to the outer end of the side plate 201, and the outer end of the outer bag 204 is fixedly connected to the positioning plate 13, and a connecting rod 208 is fixedly connected between the connecting plate 206 and the positioning plate 13. The purpose of this arrangement is that, since the aperture of the outer bag 204 is smaller than that of the inner bag 207, the dust enters the cavity between the outer bag 204 and the inner bag 207, while the large-size medicinal dust is accumulated in the inner bag 207, so that the medicinal dust in the inner bag 207 is conveniently recycled and reused.
[0024] Preferably, the outer end of the positioning plate 13 is clamped with a sealing plate 3, the outer end of the sealing plate 3 is fixedly connected to a servo motor 4, the output end of the servo motor 4 is fixedly connected to the rotating shaft 209, the inner wall of the hollow connecting column 203 is symmetrically provided with grooves, the inner part of the groove is rotatably connected with a baffle 5, the baffle 5 is semicircular and a torsion spring 6 is fixedly connected to the hollow connecting column 203. The purpose of this arrangement is that the baffle 5 can seal the entrance of the hollow connecting column 203 to prevent the dust between the outer cloth bag 204 and the inner cloth bag 207 and the drug dust from entering the grinding jar 1 again in the standby state, causing the dust inside the grinding jar 1 to be more serious.
[0025] In this embodiment, during the grinding process, the airflow blows the dust in the grinding jar 1 into the hollow connecting column 203. At this time, the inner cloth bag 207 filters the large-particle-size medicinal dust. At the same time, the dust and the small-particle-size medicinal dust enter the cavity between the outer cloth bag 204 and the inner cloth bag 207. The medicinal dust in the inner cloth bag 207 can be recycled and reused to reduce material waste. When the airflow passes through the hollow connecting column 203, the air pressure pushes open the two baffles 5, so that the airflow drives the dust into the inner cloth bag 207. In the standby state, the torsion spring 6 drives the baffle 5 to reset, so that the material port of the hollow connecting column 203 is sealed to prevent dust and medicinal dust from entering the grinding jar 1 again, causing the dust inside the grinding jar 1 to become more serious.
[0026] Example 2
[0027] like Figure 1~Figure 4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a support rod 7 is fixedly connected between the hollow connecting column 203 and the sealing plate 3, the positioning plate 13 is slidably connected to the support rod 7, and a collar is provided at the outer end of the outer bag 204, and the collar is sleeved on the outer end of the support rod 7. The purpose of this arrangement is that the slidable positioning plate 13 can conveniently discharge dust between the outer bag 204 and the inner bag 207, and the collar can support the outer bag 204 to prevent the outer bag 204 from sinking inwards and affecting the working effect.
[0028] Preferably, the outer end of the side plate 201 is symmetrically provided with a clamping groove, and the dust removal assembly 2 also includes a sealing ring 202 clamped to the outer end of the side plate 201, and the outer end of the sealing ring 202 is symmetrically rotatably connected with a spring clamp 8, and the spring clamp 8 is clamped to the inside of the clamping groove. The purpose of this arrangement is that the sealing ring 202 is provided to enhance the sealing performance of the clamping of the side plate 201 and the hollow connecting column 203, and the spring clamp 8 is provided to facilitate the installation and removal of the hollow connecting column 203 connected to the sealing ring 202, so as to facilitate the cleaning of the large-particle-size medicine dust in the inner bag 207.
[0029] Preferably, the lower side of the outer end of the grinding jar 1 is fixedly connected with an air pump 9, the outer end of the air pump 9 is fixedly connected with a hollow guide ring 10, the hollow guide ring 10 is sleeved on the outer end of the grinding jar 1, the outer end of the hollow guide ring 10 is fixedly connected with an air pipe 11 and is in conduction, the outer end of the air pipe 11 is fixedly connected with a bull horn nozzle 12, the bull horn nozzle 12 is arranged inside the grinding jar 1 and tilted upward. The purpose of this arrangement is that the air pump 9 generates airflow, and the bull horn nozzle 12 tilted upward blows dust to the top of the grinding jar 1, and the dust is quickly discharged into the hollow connecting column 203.
[0030] In this embodiment, during the grinding process of the medicinal material, the air pump 9 sends the air flow into the air pipe 11 connected to the hollow guide ring 10, and the air flow is ejected from the horn nozzle 12 at the same time, generating an inclined upward air flow inside the grinding jar 1, thereby blowing the dust to the top of the inner cavity of the grinding jar 1, and blowing the dust into the hollow connecting column 203, accelerating the filtration of the dust. When cleaning, the spring clamp 8 is rotated to remove the hollow connecting column 203 connected to the sealing ring 202 from the outer end of the side plate 201, and then the positioning plate 13 and the sealing plate 3 are loosened, and the outer cloth bag 204 is slid, and then the dust between the inner cloth bag 207 and the outer cloth bag 204 is cleaned, and the large-size medicinal material dust in the inner cloth bag 207 can be poured out from the pipe mouth of the hollow connecting column 203 and recycled.
